+# 3. Trigger Firestore event to Cloud Run
+
+Date: 2024-05-20
+
+## Status
+
+Accepted
+
+## Context
+
+We we want to listen to an event where a document is created, so we can start to load the file and resize PDF file.
+
+## Decision
+
+- Utilize [Eventarc](https://cloud.google.com/eventarc/docs/run/route-trigger-cloud-firestore#gcloud)
+- Create `firestore-trigger` service account to trigger cloud run. The path will be in the `ce-document` under the headers.
+
+Example of event trigger
+
+```
+gcloud eventarc triggers create public-on-create-trigger \
+    --location=nam5 \
+    --destination-run-service=pdf-on-create \
+    --destination-run-region=us-central1 \
+    --event-filters="type=google.cloud.firestore.document.v1.created" \
+    --event-filters="database=(default)" \
+    --event-filters-path-pattern="document=public/{docId}" \
+    --event-data-content-type="application/protobuf" \
+    --service-account=firestore-trigger@pdfun-prod.iam.gserviceaccount.com
+```
+
+## Consequences
+
+What becomes easier or more difficult to do and any risks introduced by the change that will need to be mitigated.
